Variable NDFilter

Urth Neutral Density Filters (ND Filters) cut the amount of light entering your camera to unlock motion blur and depth-of-field effects. By filtering out light, Urth ND filters allow you to open up your aperture for a shallower depth of field even in bright light. Or you can compensate for the lower light by slowing your shutter speed and creating motion blur effects without overexposing your photographs. ND filters are a crucial tool for filmmakers too as they allow you to film in bright and harsh light without overexposing or pushing your exposure settings too far. Urth ND filters give you greater creative control when there is excessive light like you’ll experience in outdoor photography and filmmaking. Urth fixed ND filters block a set amount of light, while Urth Variable NDs have a rotating element that adjusts the amount of light blocked depending on what you need. Each ND filter plants 1 tree so future generations can enjoy nature as much as we do now. All our circular filters come with a protective travel tin case, a recycled cleaning cloth, and recycled plastic-free packaging. Read more Read less

The first choice you need to make it whether to go for a Fixed ND Filter or a Variable ND Filter. A variable ND filter offers more options, which is great if you’re shooting in changing light conditions, or just starting out with ND filters. A fixed ND provides a specific light reduction and works better with telephoto and wide-angle lenses. The next choice you need to make is the level of light reduction you want. The higher the ND number, the more light it blocks from reaching your camera sensor.

Our ND filters have ultra-slim rims to avoid any vignetting issues. Our Fixed ND Filters are all in our professional Plus+ range and use the world’s best glass, making them perfect for wide-angle and telephoto lenses.

In the Hay test, powdered sulfur is sprinkled on the urine surface. It will float on normal urine, but will sink if the surface tension is lowered by the bile.

While CPL filters polarize light to remove reflections and increase colour saturation, ND filters reduce the amount of light that makes it through to your camera’s sensor, which opens up opportunities to experiment with depth of field and motion blur effects even in bright light.

What is neutral density filterused for

Fixed ND filters block a fixed f-stop of light from entering your camera. Variable ND filters provide more flexibility and have a range of f-stops you can block by rotating the outer element. If you’re starting out with ND filters, we recommend a Variable ND so you have more flexibility while you’re learning how to shoot with an ND. If the light is likely to change often, a Variable ND saves you changing between fixed NDs each time.
